CROSS-REFERENCE TO RELATED APPLICATION(S)

The present application is a 371 application of International Application No. PCT/CN2018/079151, filed on Mar. 15, 2018, which claims priority of U.S. Provisional Application No. 62/482,527, filed on Apr. 6, 2017, the contents of both of which are hereby incorporated by reference in their entireties.

TECHNICAL FIELD

The disclosure relates to wireless communications, and particularly to a method and device for determining resources and a storage medium.

BACKGROUND

In a Fourth Generation mobile communication long term evolution (4G LTE) system, a user equipment (UE) always supports a system bandwidth of a carrier, and resource allocation is performed over the whole system bandwidth.

In a Fifth Generation mobile communication new radio air interface (5G NR) system, the system bandwidth of a carrier is dramatically increased (could be up to 400 MHz). A UE may merely support or merely need to operate in a bandwidth much smaller than the system bandwidth. Therefore, resource allocation over the whole system bandwidth introduces a too large signaling overhead.

In order to solve this problem, a legacy 2-step resource assignment approach may be employed as follows. In a first step, a “bandwidth part (BWP)” which is smaller than the UE supporting bandwidth is indicated; and then the detailed Physical Resource Blocks (PRB) are indicated over the bandwidth part. And the bandwidth part is semi-statically configured by the base station, i.e., gNB.

The legacy approach as described above has the following deficiencies: carrier aggregation (CA) will also be supported in the 5G NR system. However, the legacy approach cannot support CA operation. For a UE also operating in a secondary component carrier (CC), since the UE only has the Radio Resource Control (RRC) connection with the primary CC, the UE's bandwidth part in the secondary CC cannot be configured. Hence the UE's resource in the secondary CC can still be allocated over the whole system bandwidth. This results in an excessive signaling overhead in resource allocation for the secondary CC.

DETAILED DESCRIPTION

In order to better understand the features and technical contents of the embodiments of the disclosure, the implementations of embodiments of the disclosure will be illustrated in details in connection with the drawings. The drawings are provided merely for reference but not to limit the embodiments of the disclosure.

FIG. 1 illustrates a flow chart of a method for determining resources according to some embodiments of the disclosure. As illustrated in FIG. 1, the method for determining resources includes operations illustrated in blocks. The operations may begin from block 101.

At block 101, a UE receives a first message over a first cell. Here, the first message is used for determining M first bandwidth parts (BWPs) in a second cell, M is an integer greater than or equal to 1, each of the M first BWPs is smaller than or equal to a bandwidth of the second cell; and one or more transmission resources for the UE in the second cell is within at least one of the M first BWPs.

In the embodiments of the disclosure, the UE may be a mobile phone, a laptop, a notebook computer, a desktop computer or any device that can communicate with a network device.

In the embodiments of the disclosure, the UE may receive the first message from the network device over a first cell. Here, the network device may be a base station, e.g., a gNB in the 5G NR system.

In an implementation, the bandwidth of the second cell may be a system bandwidth.

In the embodiments of the disclosure, transmission resources in the first cell may be implemented by the first carrier, and transmission resources in the second cell may be implemented by the second carrier. In an implementation, the first cell (i.e., the first carrier) may be a main cell (i.e., a main carrier), and the second cell (i.e., the second carrier) may be an auxiliary cell (i.e., an auxiliary carrier). The UE may transmit signals in a carrier aggregation manner by using the first and/or second cells.

In the embodiments of the disclosure, the UE may determine the M first BWPs in the second cell based on the first message in the first cell, so as to transmit signals by utilizing one or more transmission resources within at least one of the M first BWPs.

In the embodiments of the disclosure, the UE may determine the M first BWPs in the second cell in the following ways.

Scheme 1: the M first BWPs are indicated by the first message, and the UE determines the M first BWPs based on the first message.

For example, 3 first BWPs, i.e., BWP1, BWP2, and BWP3 are indicated by the first message, and the UE determines BWP1, BWP2, and BWP3 based on the first message.

Scheme 2: N second BWPs are indicated by the first message, N is an integer greater than M, each of the N second BWPs is smaller than or equal to the bandwidth of the second cell, and the UE receives a second message over the first or second cell, wherein the second message indicates the M first BWPs among the N second BWPs.

For example, six second BWPs, i.e., BWP1, BWP2, BWP3, BWP4, BWP5, and BWP6 are indicated by the first message, the second message is used to indicate three BWPs, i.e., BWP1, BWP2, and BWP3 among the six BWPs. The UE determines BWP1, BWP2, and BWP3 based on the first message and the second message.

In an implementation, the first message may be conveyed by RRC signaling or system information (SI).

In an implementation, the second message may be conveyed by downlink control information (DCI) or a media access control control element (MAC CE).

It is to be understood that if M=1, the first message contains information about configuration in one first BWP; if M≥2, the first message contains information about configuration in all first BWPs. In this way, the UE can determine information about configuration in the first BWPs based on the first message and perform signal transmission over the transmission resources within the first BWPs based on the information about configuration in the first BWPs.

In an implementation, the UE receives a third message over the first or second cell, where the third message indicates the one or more transmission resources for the UE within the first BWPs of the second cell. Here, the transmission resources for the UE are time-domain resources and/or frequency-domain resources for the UE, and the UE performs signal transmission within the indicated transmission resources.

In an implementation, the third message may be conveyed by the DCI or the MAC CE.

In some embodiments of the disclosure, the first message may be transmitted over the first cell, the second message may be transmitted over the first or second cell, and the third message may be transmitted over the first or second cell.

In an implementation, if the second message is transmitted over the second cell, the second message is transmitted by using the transmission resources within the first BWPs.

In an implementation, if the third message is transmitted over the second cell, the third message is transmitted by using the transmission resources within the first BWPs.

In this scheme, the UE determines the M first BWPs within the second cell based on the first message and the second message.

In an implementation, the first message may be conveyed by RRC signaling or system information (SI).

In the embodiments of the disclosure, a UE receives a first message over a first cell, wherein the first message is used for determining M first BWPs in a second cell, M is an integer greater than or equal to 1, each of the M first BWPs is smaller than or equal to a bandwidth of the second cell, where one or more transmission resources for the UE in the second cell is within at least one of the M first BWPs. Herein, a cell may represent a carrier. This innovation designed a new approach to configure from the one carrier the bandwidth part of another carrier. With the new approach, the problem is solved and the deficiency is improved as below:

1) By cross-carrier configuration of a bandwidth part, resource for a UE in a second carrier can be allocated over the bandwidth part with a much smaller size. It can significantly reduce the complexity and signaling overhead for resource allocation. Hence it enables a UE to perform an efficient carrier aggregation operation in an ultra-wideband system e.g. 5G.

2) Furthermore, it also supports dynamic selection of bandwidth part by the second carrier from a set of candidates pre-configured by the first carrier. This keeps the flexibility of bandwidth part configuration in case no perfect backhauling supporting dynamic signaling exchange exists between the two carriers.

In the several embodiments provided in the application, it shall be understood that the disclosed systems, devices and methods may be realized in other modes.
